Migrate users from Existing Windows 2003 Domain to new 2008 Domain

We have users on an existing Windows 2003 Domain, the company would like to
move users to a new 2008 Domain (new AD as they want to change the domain
name) What is the best way to go about this?

ADMT is the solution. If Exchange is involved, it's a bit more complicated.

For 2008 (run ADMT 3.1 on the 2008 side):

If Exchange is involved:

If Exchange 2003 is involved, you can use the Exmerge tool.

If Exchange 2007 is involved, you would need to use the MoveMailbox method from the source org to the target org after migrating user accounts.

This is a weak overview of the mailbox move:

I second Ace's suggestions. ADMT is the way to go. If there's project
bugdet left, you might also want to look into the Quest Migration tools
- they're somewhat easier to use. Nonetheless, ADMT is free and works fine.

Hello tom,

ADMT as already mentioned will do it. So if you use Exchange please post
the version you have. For the new domain name i would not choose the same
name as for external, if you have one.

Best regards

I agree with the others on ADMT just make sure to use the latest release
ADMT v 3.1. Previous versions do not support Windows 2008.
